+Date: Sun, 24 Jan 2021 14:20:33 -0800
+Subject: [PATCH] Remove use of include_next from c++ headers
+
+Using include_next bypasses the default header search path and lets
+files later in the include path take priority over earlier files.
+
+This makes replacing libc impossible as the default libc headers will
+occur after the libstdc++ headers, and so be picked up in place of
+headers inserted at the begining of the search path or appended to the
+end of the search path.
+
+Using include_next is a hack to work-around broken combinations of
+libraries, and is not necessary in a well constructed toolchain.

+Subject: [PATCH] arc: Update (u)maddhisi4 patterns
+
+The (u)maddsihi4 patterns are using the ARC's VMAC2H(U)
+instruction with null destination, however, VMAC2H(U) doesn't
+rewrite the accumulator.  This patch solves the destination issue
+of VMAC2H by using the accumulator, and is using a
+define_insn_and_split to generate the extra move from the
+accumulator to the destination register.
+
+gcc/
+
+	* config/arc/arc.md (maddhisi4): Use a single move to accumulator.
+	(umaddhisi4): Likewise.
+	(machi): Convert it to an define_insn_and_split pattern.
+	(umachi): Likewise.
+
+See for more details: https://github.com/foss-for-synopsys-dwc-arc-processors/toolchain/issues/427
